To. all whom it may concern:

Be 'it known that IQEIees'rUs E. VVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of h lassachusetts, have invented certain new and useful Improvements in Boot andShoe Hotttnns; and I dohereby declare the following tobe a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertainsto make and use the same.

This invention-relates to boots and shoes, and particularly to that part oifa boot or shoe which includes the out sole and heel. and is commonly designated as the bott'ornf In the prior art certain styles of boots and shoes have embodied outsoles .com-pris ing a short sole and .aheel-seat portion in abutting relation, and to which the heel is attached'f The shortfsoleis of 'ziigootl grade of sole'fleather and is of theusual form and character from the toe to substantially the rear end of the shankportion. The heel-$6517 Portion is" of'leather of an in- 'feriorxcharacter and is of such formjas to make, in conjunction with the short sole, "an outsole of the commonly employed co'1itou1. Bythis expedient, a 'material saving ofexpensive leather lsfefi ctefl,Whllfl.

the inferior and'ch'eape'r leather of the heelseat portion possesses'thev necessary characteristics toenable it to take a satisfactory randing cut, a key-Wheel "marking, and ulti- One ofthe objeotsoli' thefpresent inven tion is to ,efilect further economies in leather and inthe expense of manufacture of boots and shoes, and tovprovide a relatively cheap bootf orshoe bottom that shall possess the nsual lwearing qualities shall embody a clean-shaped, smooth and durable randing, a distinct and permanent beading or keywheel marking, anda satisfactory ultimate finish or polish that shallcompare favorably with that of the boot or shoe bottoms of the ipriorar t.

One feature of the present invention resides in :the employment of aheel-seat portion of, ordinary commercial leatherboard or other analogous leather or paper composition ,whie'h has been subsequently treated and compressed. This leatherboa'rd heel- Seat'portion is preferably prepared in the general manner set forth and claimed in a copending application Serial No; 213,681, filed Jan. 1918, by -the present applitrimmingis requisite, whereby the benchcial. surface characteristics thereof are remass to facilitate and rendenspecially ef- 'l'ective'the subsequent finishing operations.

'Other obj'ects of the invention and, features. by which they are attained will become apparent from the following description in connection withthe illustrated preferred embodiment of the invention.

.Throughout the specification and" claims the term leatherboard is used ina generic [sense tonnclude any of the cheaper and analogous grades of ordinary commercial heel-stock material or leather, paper or other suitable C OmP OSItIOIIS, the properties and characteristlcs of which are unsuited for the present purposes, I

Theinvention willbe most readily undercant, and, by reason of its preparation, its

stood by a reference to the accompanying drawing which illustrate-s the preferred embodiment-of the invention, in whlch 'Flgure 'l.

is a plan-view of a'two-piece boot or shoe outsole embodying the invention; F i'g. 2 is a view in side elevation of the outsole illustrated in Fig; 1; and Fig. 3 is a view in jthe manner above indicated. The short sole 1'2"i's ofthe ordinaryforn from theitoe to substantially the rear end'ofthe shank portion, which vend 'is'scarfedtin order that it may. be placed in ab'utting relation to asirnilarly beveled end of the treated and compressed leatherboard heel-seat portion 14:. the two component members being preferably united together by staples, or other suitable means, to constitute a unitary outsole that may be attached to a lasted shoe in accordance with customary practice.

The heel-seat portion 14 is composed of the usual commercial leatherboard that has been shaped, treated and subsequently compressed and condensed in the general manner set forth in the above mentioned copending application. More specifically, the heelseat portion 14 is dinked or otherwise formed to definite shape from a sheet or piece of ordinary leatherboard, after which a randing 15 is cut around the upper edge thereof and its surface, and particularly its edges, are then filled with a suitable sizing material that penetrates the surface to an appreciable depth. The sizing is then permitted to dry to a greater or less extent, and the shaped and treated heel-seat portion is then placed in a mould and heavily compressed to its final size and form. This treatment and subsequent compression results in condensing and compacting the leatherboard and producing an impregnated surface of appreciable depth that is smooth, hard, and durable, and particularly adapted to. take a permanent and distinct key-wheel marking, and a superior, ultimate finish or polish. The surface qualities of the initial leatherboard are thus improved and modified and rendered adaptable for the purpose intended.

The dinking and rand-cutting of the heelseat portion to definite shape is of particular importance, for the reason that the shaped heel-seat portion is adapted to closely fit within the mould throughout its entire surface, whereby the pressure to which it is subjected is uniformly distributed, thus resulting in a more uniformly consolidated and condensed article. Moreover, the dinking and rand cutting operations roughen the edges and open the pores thereof, so that the penetration of the sizing material is facilitated and rendered especially effective.

The sizing or filling step is also of importance, in that the sizing material penetrates the pores and serves to raise or turn out the exposed fibres which are subsequently turned in and compacted to form a surface having improved and modified characteristics and properties which materially aid and con tribute to the durability and subsequent finish of the article.

After the two-piece outsole has been attached to the lasted shoe in any well-known manner, a treated and compressed leatherboard heel 16 of final size and form, such as is produced by the method set forth in the above-mentioned copending application, is positioned in registry with the treated and condensed heel-seat portion 14 and secured in position in any suitable manner. The relative proportions of the component parts of the bottom are so chosen that the heel when positioned upon the shoe overlaps the short sole 12 and thus covers the joint between it and the heel-seat portion 14.

A leather top-lift 18 is then attached and the completed heel comprising the treated and compressed leatherboard heel-seat portion 1%, heel 16, and leather top-lift 18, are lightly secured, and the subsequent ordinary finishing operations, including the beading or key-wheel marking, are performed.

By reason of the fact that the heel-seat portion 14 and heel 16 are initially made to final size and form and are positioned in registry the one with the other, no further trimming thereof is necessary, and a light scouring is sufficient to ren'iove any slight roughness or protuberances, so that the surface is not removed and the beneficial qualities of the improved and modified lateral surfaces are retained to improve the ultimate finish and facilitate the finishing operations. Moreover, these qualities lend themselves toward a smooth and clean-shaped randing, and a distinct and permanent key-wheel marking, all of which contribute to a finished heel that com )ares favorabl' in durability, appearance and finish with those of the prior art that haveflembodied heel-seat portions of leather in lieu of relatively cheap leatherboard material. 1

Obviously, the invention is not restricted to the specific structural details and arrangement and location of parts set forth in connection with the illustrative embodiment thereof, and modifications may be made therein Without departing from the spirit and scope of the invention.

Having thus described the invention and its preferred embodiment, that which is claimed as new is 1. A boot or shoe outsole comprising a leather sole portion and a heel portion of commercial leatherboard that has been sized and compressed to the final size and form in which it is to be used in a finished shoe.

2. A'boot or shoe outsole comprising a leather sole portion and a heel portion of commercial leatherboard that has been cut to shape, surface-sized and compressed to the final size and form in which it is to be used in a finished shoe.

3. A boot or shoe outsole comprising a. leather sole portion and a heel portion of commercial leatherboard that has been sized and compressed to final size and form to give it a lateral surface of appreciable depth having improved and modified characteris tics rendering it capable of being beaded and finished in a manner comparable to leather.

4. A boot or shoe outsole comprising a leather sole portion and a heel portion of commercial leatherboard that has been cut to shape, surface-sized and compressed to improve and modify its surface characteristics and produce an ultimate surface that may be finished in a manner comparable to leather.

5. A boot or shoe outsole comprising a leather sole portion and a randed heel portion of commercial leatherboard that has been sized and compressed to the final size and form in which it is to be used in a finished shoe, said form includin a cleanshaped, smooth and durable randing.

6. A boot or shoe bottom comprising a short sole of leather, an adjoining heel-seat portion composed of commercial leatherboard that has been sized and compressed to final size and form to give it a smooth, hard and durable lateral surface which is retained in the finished shoe, and a heel of final size and form attached to said heel-seat portion in registry therewith,

7. A boot or shoe sole comprisin a forepart portion of quality outsole stodlr, and a complete heel portion of stock of inferior uality attached thereto and forming with the .orepart a solid outsole, said heel portion having the fibers of its lateral surface modified and hardened to render said surface caforepart andshank of leather and a heelseat secured thereto of stock of inferior quality, said heel-seat being surface-sized, cut and compressed thereby having its surface characteristics modified and a hardened edge produced having a surface approximating leather.

9..A boot or shoe bottom comprising an outsole composed of a short sole of suitable outsole stock and a heel-seat attached thereto of stock inferior to outsole stock, and a heel of final size and formattached to said outsole, said heel-seat having been surface sized and compressed to final size and form producing a hardened lateral surface capable of taking a finish comparable to that of the adjoining sole and heel surfaces without trimming.

10. A boot or shoe sole comprising a forepart portion of suitable outsole stock, and a heel portion of stock of inferior wearing quality that is heel-shaped in plan and has been hardened by both lateral and transverse compression and shaped to a size and form for exact registration with the heel seat of the heel to be used in the finished shoe.
